Description
Technical Field
The invention relates to the technical field of payment transaction, in particular to a transfer payment method based on a block chain technology.
Background
Currently, with the large-scale growth of internet and mobile phone users, internet payments and mobile phone payments are rapidly developing. Meanwhile, the supervision department finds that a large merchant mode and a second clear mode are used by a plurality of platforms in the actual business process. The 'big merchant' mode refers to the condition that a plurality of merchants commonly use one merchant code, and the authenticity principle of the merchants is violated; the 'second clear' mode refers to that a payment company or a bank transfers settlement money to a certain company or a certain person, and the settlement is carried out on the settlement money to a merchant by the certain company or the certain person, so that the principle of directness of settlement is violated. The situation that funds are retained in the platform account can happen, and once the platform runs or the funds are stolen, a series of problems with extremely bad influence can be caused when the account funds reach a certain scale. Meanwhile, the authenticity of the transaction information provided by the platform cannot be guaranteed, and there may be behaviors of counterfeiting and changing transactions to collect the funds of merchants and users.
The block chain has the characteristics of decentralization, openness, autonomy and information non-falsification, can be used for constructing a supervision tool box which is required by a supervision department and comprises a plurality of means, is beneficial to implementing accurate, timely and more-dimensional supervision, solves the problem that online commercial service platforms and offline payment service providers are suspected to be clear, and is more common in transfer payment, so that the transfer payment method based on the block chain technology is produced.
At present, in the payment method based on the block chain technology, an independent foreknowledge system is not used for monitoring the transaction or payment request on the block chain, or the independent foreknowledge system is connected with a payment channel, and the payment data is verified and transmitted through the foreknowledge system, so that the transfer payment method based on the block chain technology is firstly proposed in the payment field.
Disclosure of Invention
The invention aims to provide a transfer payment method based on a block chain technology, which can effectively avoid the risk defect in the existing order system. By utilizing the characteristic of the block chain distributed account book, a monitoring mechanism can monitor all transactions in the system in real time, and the problems of secondary clearing and the like are avoided.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for payment transfer based on blockchain technology, comprising:
s1, user order submission: the information of the user and the transfer party generates a payment request;
s2, submitting a payment request by the merchant system: the merchant order system submits the payment request to any one node on the block chain payment system, and at the moment, the node forms a receiving node;
s3, block chain processing step: after the block chain verifies the payment request, the verified payment request is blocked by a consensus algorithm, so that the payment request is recorded on the block chain;
s4, monitoring and paying steps: the method comprises the steps that a first known system monitors a payment request on a block chain of a node matched with the first known system, and sends the payment request to a payment channel; the payment channel processes the payment request and returns a payment result to the precedent system; the known system returns a payment result to the block chain through the matched block chain link point;
s5, payment result processing step: after the payment results are blocked by a consensus algorithm, the payment results are recorded on a block chain and are notified to an order system of a merchant;
and S6, ending the payment.
Further, the block chain processing step (S3) is specifically:
s3.1, the receiving node receives the payment request, verifies the payment request, broadcasts the payment request to other nodes of the block chain if the verification is successful, simultaneously stores the payment request in a transaction pool of the node, and goes to step S3.2; if the verification fails, directly discarding the payment request and ending the payment;
s3.2, after receiving the broadcasted payment request, other nodes of the block chain respectively carry out verification, if the verification is successful and the payment request is received for the first time, the other nodes broadcast the payment request and simultaneously store the payment request into a transaction pool of the node, otherwise, the node directly discards the payment request;
and S3.3, after the preset time, blocking the payment request through a consensus algorithm, and recording the block to a block chain.
Further, the step of monitoring and paying (S4) is specifically:
s4.1, monitoring a payment request on a block chain of a node matched with the payment request by a first-known system, verifying the payment request, if the verification is successful, sending the payment request to a payment channel, and entering the step S4.2, if the verification is failed, discarding the payment request, and ending the payment;
s4.2, processing the payment request through a payment channel to generate a payment result;
s4.3, the payment channel sends the successful payment result to the precedent system, the precedent system verifies the successful payment, and if the successful verification is achieved, the payment result is written into the matched block chain link point; and if the verification fails, discarding the payment result and not recording.
Further, the payment result processing step (S5) is specifically:
s5.1, the block chain node matched with the priori knowledge system receives the payment result written by the priori knowledge system, verifies the payment result, if the verification is successful, sends the payment result to other nodes of the block chain, and simultaneously stores the payment result into a transaction pool of the node; if the verification fails, directly discarding the payment result;
s5.2, after receiving the broadcasted payment result, the other nodes respectively carry out verification, if the verification is successful and the payment result is received for the first time, the payment result is broadcasted, and meanwhile, the payment result is stored in a transaction pool of the nodes; otherwise, directly discarding the payment result;
s5.3, after the preset time, recording the payment result on a block chain after the payment result is blocked by a consensus algorithm; and S5.4, returning the payment result on the block chain to the merchant order system by the node which receives the request at the earliest.
Further, the payment result processing step (S5) further includes:
and S5.5, after the merchant order system receives the payment result, displaying the payment result.
Further, in step S4.3, after receiving the payment result, the block chain link point matched with the pre-known system also verifies the payment result, sends the verification result to other nodes of the block chain after the verification is successful, and simultaneously stores the payment result in the transaction pool of the node; if the verification fails, directly discarding the payment result; after receiving the broadcasted payment result, the other nodes respectively carry out verification, broadcast the payment result and store the payment result into a transaction pool of the nodes, wherein the verification is successful and the payment result is received for the first time; otherwise, the payment result is directly discarded.
Further, the payment data which fails to be verified is processed by an error checking and processing system connected with the blockchain, wherein the payment data comprises data of a payment request, a payment response, a payment result and a settlement result.
In addition, in the invention, after other nodes of the block chain receive the broadcast, the node discards the payment data, which means that only the node with the verification failure discards the payment data, but not all the nodes discard the payment data, and the payment data also exists in a certain node or certain nodes of the block chain.
